About Opto 22

Opto 22 was founded in 1974 by engineers who designed a better solid-state relay and chose to build it in a non-corporate, flat organization. Over 30 years later, we're still privately held, lean, and run by engineers. And our I/O, controllers, software, and SSRs are famous for their quality and reliability.

All our products are manufactured at our headquarters in Temecula, California. Each hardware item is individually tested-twice. Customers comment about their dusty, 20-year-old "Optos" still doing the job in the back of a factory somewhere.

With this kind of quality, we can afford to provide FREE customer service with every product. SSRs and most I/O modules are guaranteed for life.

Our flat organization fosters individual responsibility, quick response to customers' needs, and fast development of cutting-edge products. Our products are based on open standards and commercially available Internet and computer technologies, not on proprietary systems.

For industrial automation, discrete manufacturing, process control, remote monitoring, and data acquisition, let us show you the Opto 22 difference.
